In game tactics discussion

Hi, with Tactics being officially released for a while now.. and with a load of recent updates and tweaks I think it would be cool to share everyones tips and tricks they have when raiding. Personally, I've started off new account several times and tried out each of the earlier unit (up to 10,000 resources) Not sure why I've done it, mainly for a test more than anything. Do you guys have anything worth sharing? Some tips when going on a raid or preparing for a raid?
